Potential top NFL draft picks have disappointing day at combine

INDIANAPOLIS — On the first full day of workouts at the NFL combine, the biggest waves were caused by two players who didn't even lace up their running shoes.

Alabama OT Andre Smith . Once a candidate for the first overall pick, Smith hurt himself by leaving the combine and failing to notify his group leader. Smith claimed that because he opted not to work out, he thought he could leave. His actions left NFL executives shaking their heads.

Texas Tech WR Michael Crabtree . Tests revealed he has a stress fracture in his foot, and he will need to have a screw surgically inserted. Crabtree said he plans to postpone surgery so he can work out on his pro day March 26.

Oklahoma State TE Brandon Pettigrew . He's supposed to be the top tight end in the draft, but Pettigrew (above) was unimpressive in almost everything he did, including his 4.87 40-yard dash.

South Carolina TE Jared Cook . He took the triple crown among tight ends -- best 40 time at 4.5, best vertical jump at 41 inches and best broad jump at 10 feet 9 inches. He could have helped himself more but did not go through positional drills.

South Carolina OT Jamon Meredith . Scouts say he looked very fluid in drills, and he had the second-best 40 among OTs.

Nebraska OT Lydon Murtha . He was tops among offensive linemen in the 40, the three-cone drill and the 20-yard shuttle.

Virginia OT Eugene Monroe . In positional drills, he looked like the best athlete on the field.
